Any pics of silicone stains on paint from tire shine?

Did a search already..



I did a training project in my company's bodyshop a few months ago and a couple of brand new Jeep Liberties had suffered from silicone stains on their paint. The dealer had "detailed" the cars when they sold them to the customer, and used a cheap, silicone-based tire shine. The result? A browning/yellowing on the quarter panels that required repainting.



A friend of mine is extremely cheap and very stubborn. She's in college, so she's broke. But she loves the Z28 that her folks bought her. A couple of years ago, I did a Zaino treatment on the car for her, and it came out really well. But since then, she kinda just wings it (IMHO) with store-bought basic stuff. I noticed that on her ground effects, there were some yellow spots. When those two Jeeps came in my bodyshop, I realized what her yellow spots were - silicone stains from using Black Magic.



However, even to this day, she still uses Black Magic tire shine. I think it's junk, and that she only buys it because it's the cheapest tire shine at Wally-world. So what I'm looking for is a verified picture of a silicone stain on a car's paint. She's being stubborn as usual, and won't listen to a voice of wisdom. Thanks. :)
 
A "verified picture"? Hmmm.... is this for a court case or something?? ;)



Even if you can prove it to her, she isn't going to change her mind, is she? I mean, think about the futility of a man trying to change the mind of a stubborn woman.......



Just trying to interject some common guy sense into your situation. My suggestion is to let her do whatever she wants. It's her car.



Whatever you do, tread lightly, comrade.
 
It's the big brother effect. I've gone through countless episodes of "I told you so" with this girl. But she never listens. I wanna chalk up another one. :)
 
Correct me if I'm wrong, but I don't think that there is any evidence that silicone-based tire dressings cause "stains" or "yellow spots" on properly applied or factory clear-coat paint finishes.



If you have info otherwise, please share............



My understanding is that auto body shops dislike silicone-based products (i.e. Armor All) because they cause "fish eye" or crater like defects on repainted surfaces. This is essentially a prep failure, since proper prevention with PREPSOL or equivalent product is effective against fish eye.
 
Why not show her a bottle of tire shine where it says on the label not to use it on light colored vehicles due to the danger of stain from tire sling. I think I saw that once on Armour-All.



FYI, it's the creosote that's in the tire rubber that is released by the dressing that causes the stains.
